问题 The author refers to the ocean bottom as a "frontier" in Paragraph 1 because it ______. [br] The word "extracting" underlined in Paragraph 2 is closest in meaning to ______.

选项 A、breaking
B、locating
C、removing
D、analyzing

答案 C

解析 由extracting和Paragraph two定位到原文第二段最后一句... the Glomar Challenger,was able to maintain a steady position on the ocean’s surface and drill in very deep waters,extracting samples of sediments and rock from the ocean floor.[精析] 语义理解题[考频:37]。本题考查某个单词在原文中的含义。根据原文可知,Glomar Challenger能够在水平面上保持稳定状态,并钻入深水中,这样就从海底抽取沉积物和岩石的样本。extracting“拔[抽]出,取出,摘出,撤出”,故C)为正确选项。[避错] A)打破,B)定位,D)分析,这三项意思都不符合,全都排除掉。
